Syntax of range()
start: integer starting from which the sequence of integers is to be returned. stop: integer before which the sequence of integers is to be returned. The range of integers ends at stop – 1. step: integer value which determines the increment between each integer in the sequence.

Why we use range-based for loop?

Use the range-based for statement to construct loops that must execute through a range, which is defined as anything that you can iterate through—for example, std::vector , or any other C++ Standard Library sequence whose range is defined by a begin() and end() .
